We mapped the geomorphologic units of the Gale crater central mound and the proposed Mars Science Laboratory landing site, developed an inferred stratigraphy, and assessed hypotheses for the origin of the mound. Key findings include: sinuous inverted channels in the landing ellipse, cemented fractures in the lower mound, and possible cross-beds in the upper mound unit suggesting an aeolian origin for the upper mound.
